Gravesend · TR19 Grease
We clean the full commercial duct run - grease, dry and laundry ductwork, canopy to roof fan - for kitchens, offices and industrial sites across Gravesend, and certify it to the TR19 Grease standard your insurer expects.
Gravesend
Gravesend rates around 800 food premises, and behind a large share sits an extract duct a canopy clean never reaches - plus the dry ductwork and air-handling that keep its offices and public buildings running.
Kitchens across Gravesend work out of tight, mixed premises - Windmill Street, Parrock Street, St Georges - their extract snaking through concealed voids to roof-mounted fans. We take the whole run to the TR19 Grease standard, hood to fan, reaching the horizontal legs and vertical risers a canopy wipe never touches.
Beyond the kitchens, we clean the dry ductwork and air-handling in offices, schools and public buildings, and the lint-heavy laundry ducts in hotels and care homes. High-output kitchens - the North Kent College Gravesend campus, Gravesham Community Hospital, Stonebridge Road and the town hotels - lay grease down fast in exactly the concealed sections where a fire travels.
The standard
TR19 Grease is the benchmark Gravesend insurers and fire risk assessors expect - measured across the whole extract run, not just the visible mouth of the canopy.
The standard works in grease-film thickness, fixing the depth at which a run must be cleaned and re-tested. In the shared roof voids around Windmill Street and St Georges, wiping the canopy and filters leaves the ductwork - the long concealed sections that gather grease and carry fire - untouched. We open the full Gravesend run through existing and newly cut inspection hatches, strip it to bare metal, log grease-depth readings at fixed points before and after, and issue a TR19 Grease certificate with the post-clean depths recorded.
By system
The fire risk. Fried-food extract coats duct walls in combustible grease; cleaned canopy to fan and certified to TR19 Grease.
Supply and general extract in offices and public buildings, carrying dust and debris that throttles airflow and loads the air-handling unit; cleaned to TR19.
The hidden one. Tumble-dryer ducting packs with lint - highly combustible - in Gravesend hotels, care homes and gyms.
On the ground in Gravesend
We are in Gravesend's ductwork and plant every week. The proof is the jobs, not the stock photos.
A launderette in Gravesend had large amounts of flammable textile lint packing the main horizontal dryer exhaust runs. We ran high-powered vacuum extraction with pneumatic air whips to clear the long runs, cutting the drying-cycle times and removing a critical fire hazard. We advised the owner on fitting an inline condensation trap to keep the collecting lint dry, and lagged the cold section where the damp was forming.
When it is due
Ductwork rarely warns you politely. In a busy Gravesend kitchen these are the tells.
Smells pushing back into the dining room, a canopy that drips onto a Windmill Street cookline, extraction that no longer clears the steam, visible grease at the filter edges, or a Gravesend insurer or fire risk assessment asking for a TR19 certificate you cannot produce. Cleaning frequency tracks use - a hard-frying Parrock Street kitchen needs it far more often than a daytime cafe - and your certificate states the interval, so the next clean is never a guess.
How it runs
Inspect the full Gravesend run, find the access gaps in the concealed sections, agree scope and frequency.
Fit inspection hatches where the run is sealed - common in the older St Georges conversions - and protect the kitchen.
Canopy to roof fan, down to bare metal, with before-and-after grease-depth evidence.

Why it matters
Three duties push every Gravesend operator to keep ductwork clean, and they reinforce one another.
Fire safety law. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for a Gravesend premises must assess and manage fire risk. A grease-laden duct is one of the most serious risks in any catering building, because a flare-up on a Windmill Street cookline can travel the ductwork and spread fire through concealed voids. The Health and Safety at Work etc. Act 1974 and the HSE reinforce the same duty of care.
Insurance. A live TR19 Grease certificate is what a Gravesend insurer treats as evidence the system is maintained. Miss it and a fire claim may be reduced or refused - an expensive surprise once the damage is done.
Hygiene and environmental health. Gravesham Borough Council food hygiene inspections assess the physical condition of premises, ventilation included. A grease-clogged system can count against the rating an Environmental Health Officer awards, quite apart from the smell and the falling extract performance your staff have to work in.
It is set by cooking hours under TR19 Grease - roughly every three months for heavy use of 12 to 16 hours a day, every six for moderate, every twelve for light. A hard-frying Windmill Street kitchen sits in a tighter band than a daytime Parrock Street cafe. We measure the grease load and confirm your interval.
The full run, canopy through the concealed horizontal and vertical ductwork to the roof fan - the hidden sections a canopy-only clean leaves loaded, which matters in the tight stock around Windmill Street and St Georges where the runs are long and awkward.
Yes. We clean the dry ductwork and air-handling in Gravesend offices, schools and public buildings, and the lint-heavy laundry ducts in the Kent hotels and care homes, alongside kitchen grease ducts.
Little, if it is planned. We survey the Gravesend run first, agree a slot overnight or on a close day, sheet off the kitchen and clean section by section, so a Parrock Street cookline is back in service for the next shift.
Yes - from Windmill Street and Parrock Street kitchens to the offices, schools and industrial units across Gravesend and the wider Kent.
Yes. We work overnight, early mornings and closing days for the Windmill Street and Parrock Street kitchens, and around shift patterns at commercial and production sites, at no extra charge for out-of-hours work.
We fit compliant access panels where the ductwork has none, so every internal section can be reached, cleaned, inspected and certified - common in the older St Georges conversions where the run was boxed in with no hatches.
